供应G2273AS2U-3A高效COT同步降压转换器

GMT致新 G2273AS2U AQFN2X2-12 3A高效COT同步降压转换器

General Description
The G2273 is a monolithic, step-down, switch mode
converter with built-in internal power MOSFETs. It
achieves 3A continuous output current from a 2.6V to
5.5V input voltage with excellent load and line regulation.
The Output voltage can be regulated to as low as
0.6V. At medium to heavy loads, the switching frequency
is 1.5MHz. At light load, the device automatically
enters PSM to maintain high efficiency.
The Constant-On-Time control scheme in G2273 provides
fast transient response to be optimized over a
wide range of loads and output capacitors. Thermal
shutdown and cycle-by-cycle current limiting are used
for protection.
The G2273 is available in an AQFN2X2-12 package.
